ENGINE-HOUSING.

Specification of Letters Patent.

Patented June 18, 1918.

Application led January 10, 1917. Serial No. 141,548.

To all whom t may concern Be it known-that I, THOMAS E. MURRAY, a citizen of the United States, residing at NewYork, in thecounty of New York and State of New York, have invented a certain new and useful Improvement in Engine- Housings, of which the following is a specification.

The invention is an engine housing more particularly designed for gas engines, and consists in the construction hereinafter set forth, whereby the parts are made of struck up, stamped or pressed sheet metal, and where permanently united, connected by electrically welded joints. The object is to simplify and cheapen the construction.

In the accompanying-drawings- Figure 1 isan elevation 'of my housing, showing the cover in vertical longitudinal section. Fig. 2 is a horizontal section on the line y,.y of Fig. 1. Fig. 3 is a transverse section on the line w, 0c of Fig. 1. Fig. 4 is a detail section on the line y, y of Fig. 6'. Fig. 5 is a detail section on the line e, a of Fig. 6, and Fig. 6 is a top view-the fastening bolts being in section.

Similar letters and numbers of reference indicate like parts.

1, 2,3, 4 are cylinders of a gas engine, having their ends 'preferably electrically welded, as shown at 5, 3), to circular flanges surrounding openlngs in plates 6 and 7. 8 is an elongated cup-shaped water jacket, having circular openings in its bottom, through which pass the cylinders 1, 2, 3, 4. Said openings are flanged, as shown at 9, Fig. 3, and the flanges are welded to said cylinders. The upper edge of the jacket 8v is outwardly flanged, as shown at 10, and this flange is welded to the under side of plate 6.

In the plate 6 are a number of circular openings 11, 12, 13, 14,115, 16, 17, 18, which form seats for the engine valves-one of which valves is shown at X, Fig. 3. A box 19 covers the opening 11; a box 20 covers the openings 12, 13; a box 21 covers the openings 14, 15; .a box 22 covers the openings 16, 17, and a box 23 covers the opening 18. These valve boxes are all electrically welded at their upper edges to the under side of plate 6. In their outer walls are openings 24, Fig. 1, for the usual gas and exhaust ducts.

A cover, generally designated by A, is

placed upon the late 6, and is constructed as follows: B, D,'E are four similar quadrangular inverted boxes of sheet metal placed side by side and preferably electrically welded together at their meeting faces. Each box or compartment covers a cylinder opening and the two valve openings associated therewith (as the cylinder opening at 1, Fig. 2, and the associated valve openings 11, 12) and its upper wall F forms a head for the-cylinder so covered, an upper closure for the valve chamber above plate 6, and in coperation with plate 6, a passage G from said valve'chamber to said cylinder (see Fig. 3).

Inclosing all of the inverted boxes B, C, D, E is a single inverted box H, the vertical end walls of which may be electrically welded to the walls of the end boxes B, E. Between the upper walls F of boxes B, C, D, E and the upper wall I of box H is a space J which communicates, through openings in its end walls, with the ducts K. These ducts have each a top wall registering with the top walls of boxes B, E and end and side walls. The bottoms of said boxes are o en and come immediately above openings in plate 6, which openings communicate with water jacket 8.

In the top wall I of box H is an elongated oppning, covered by an upward extension. in one inclined side of which is a tube M. Water admitted to the jacket 8, as by pipe P, Fig. 3, fills the said jacket and ducts K, passes to the space above boxes B, C, D,.E, and then escapes by extension .L and tube M, to which tube a pipe for conducting away said Water may be attached.

In the wall I, I form downward tubular projections Q, which are internally threaded and shouldered to receive spark plugs-one shown in dotted lines at R, Fig. 4. I also form in said wall smaller tubular downward openings S, Fig. 5, for the reception, of headed 'bolts T, said bolts passing through openings in the top walls I, F of the boxes B, C, D, E, and being threaded at their ends to engage in plate 6. Said bolts serve to bind the boxes together and to the plate 6.

The cover A is detachably secured upon plate 7 by lugs U on the ends and sides of box H and bolts V passing through said lugs and entering plate It is now to be noted that the cover A is made of sheet metal-preferably steelwith all its parts produced by stamping, striking up or pressing, and thatvvhere said parts are united, this is done by electrical welding, so that the entire cover is homogeneous in material. Thus the several parts are (a) the boxes B, C, D, E, which may be all alike and each Stamped out of a single piece of sheet metal-(b) the inclosing box H, With its flanged openings S and Q `and upward extension L. This also may be stamped yfrom a single piece of sheet metal. And lastly (c) the ducts K, which are alike and each also stamped from a single piece of sheet metal.

The cylinders 1, 2, 3, 4L are simple tubes. The plates 6, 7 With their openings, as described, can each be stamped from a single iiat plate. The Water jacket 8. may also be stamped from a single piece of sheet metal, and so may each of thepvalve boxes 19 to 23, inclusive.

The cover A is secured 4on plate 6 by bolts,

so that it can be removed as desired to afford access to the parts; but,l if desired, it may be permanently attached to plate 6 by electrically Welding to said plate the edges of the several boxes and ducts K.

By reason of this construction, I can produce the Whole housing from tough sheet steel, at small expense and With accuracy, and Without any machining. Where a number of housings are made, the several parts may be interchangeable and produced in large quantities, and assembled as desired.
